Conceptual design of wearpack with physiology detector feature based on wearable instrumentation

Abstract We describe an architecture for conceptual mechanical modeling. It combines tools for parametric geometry and variational modeling using a feature-based representation. Parametric geometry allows designers to represent families of components as a single parameterized model. Variational modeling allows designers to model mechanical concepts analytically using equational constraints, and to evaluate competing alternatives common during conceptual design. Feature definition facilities allow designers to build libraries of frequently used mechanical components, by collecting interacting components into single higher level entities (features), and defining ways to interact with them. All of these capabilities are needed for conceptual design, and play complementary roles. Integrating them, and clarifying their inter-relationships, is essential to building an architecture supporting conceptual design. To this end, we have implemented this architecture in an experimental CAD system.

The Cost

The developing new products of high quality, low unit cost, and shortening lead time to markets are the key elements required for enterprises to obtain competitive advantages. In order to improve the creativity and shorten lead time to markets, a methodology of automatic virtual entity simulation of conceptual design results is proposed. At the end of conceptual design, the conceptual design results are expressed in the symbolic schemes generated by the computerized approach with a higher capability to obtain the innovative conceptual design. Then, the symbolic scheme is identified into basic mechanisms and their connections. To the identified basic mechanisms, their kinematic analysis is carried out by matching basic Barranov trusses, and their virtual entities are modeled based on feature-based technique and encapsulated as one design object. Based on the structures of the basic mechanisms and their connections, a space layout to the mechanical system corresponding to the symbolic scheme is fulfilled then. With the pre-assembly approach, all parts in the mechanical system are put onto proper positions where the constraint equations are met. In this way, the virtual entity assembly model of the mechanical system corresponding to the symbolic scheme is set up. Changing the positions of the driving links continually, the virtual entity simulation of the mechanical system will be fulfilled. As a result, with the aid of this approach, we can not only obtain innovative conceptual design results with excellent performances, but also shorten the design time and the cost of product developments.
